Glad you liked it, I had fun. As usual things started off slow and then got better and best toward the end of the show. I played music from a ChucK-based software linear CMOS model implementing a boolean sequencer clocked at audio rates into a block of approximately 32 linear CMOS amplifier summed to the output.

I talked about CMOS theory but just analagously using the water tower example of pipes and valves representing wires and transistors. Then we took a tour of the linear CMOS thread in the Lunetta subforum and finally I talked about the software model while modifying it and playing many examples.

This week's show turned out quite well, I'm sure you will enjoy it - lots of weird sounds and I even got the voice modulation working pretty well after a bit of rewiring during the show. Was lots of fun, enjoy!

Just finished listening to this last show. Most enjoyable. Thank you. It's widened my understanding and given me some new techniques to experiment with.

Anyway, you asked for comments so here goes...

I 'm a beginner, but there was nothing in the show I couldn't understand. Don't be afraid to crank up the complexity a little. We can always pester you in the forum or the chatroom, and the more discussion generated the better surely?

I'm not sure about splitting up the show into sections. You should do whatever you enjoy best. I always appreciate any kind of instruction in electronics, but it was also enjoyable when you improvised your circuit, swapping wires and so forth. Any sort of unexpected results and discoveries are great, and are in the spirit of live transmission and lunettas in general.

I have a couple of questions. Hope you don't mind me firing them at you. If you like you could answer them on the next show, or here on the forum. Or not at all.

1. How is it that the logic 'cloud' seems to add harmonic content to the signal? Is it doing anything other than rearranging and mixing square waves of various frequencies?

2. AC-coupling - this is a new concept for me. You used it a few times in this circuit. Am I right in that the reason you used it was to act as a sort of high-pass filter to isolate the higher frequencies from your voice? Assuming I haven't already got this wrong already, why is this? Would the higher frequencies of your voice more efficiently modulate the frequency of the oscillator, and if so, why?

3. What other sources of modulation input might we explore? There's voice and guitar obviously. What about intentionally picking up radio interference? (this is more a thinking aloud than a question...)

Here is an hour long show in which I tell all there is to know about the emSynth project / hobby business of ours / mine. Great if you're into inexpensive yet awesome sounding miniature modular synthesizers.

This was an excellent interview with Psyingo, or Phil, whose music is under the name Ruin. The music is great, the conversation wonderful, and I gained a new friend in the process - nothing better than that!

Really enjoying the interview show with psyingo, and the music! I missed it when it aired and it's nice to have it posted here to listen to later. +1 to those living in poverty and confined spaces. You're not alone. More of the interview shows please Les! Great show guys!

OK so that last message was the end of December. 2012, and now it's the end of December 2016. I've been away for four years this time. I popped in once in a while but never really returned. Well I'm back. Back with full intent of staying put here, not letting petty differences pull me away. Here's why.

I'm faced with my own mortality. I have gained weight, a lot of weight. I now tip the scales somewhat above 500 lbs. Yeah I know. So it's lose it or lose it for me. I'm working on controllers that translate body motion into control signals. for the purpose of creating music with body language.

Succinctly put: The Les Hall Show is back!

This new 2017 edition will begin with a rambling series of recordings aimed at introducing exercise using Pure data (Pd). At Howard's recommendation I'm getting into Pd. The mosc is wise, and I obey!

So we begin with some disorganized audio soon to get better. Here goes...

Here is one of the recent recordings made yesterday. I'm not going to post them all, as that would be laborious downloading. I might put them somewhere though for public availability. Anyone know how to auto-post long segments of audio?

This show was recorded with my friend Ixmal Supermarine of London, England. We talked about Shure microphones and I felt nervous the whole time for some reason. Ixmal knows more about microphones than I thought, and I know very little... Was a good show!
